PNT stands as an essential utility of modern society, spanning across sectors such as defense, disaster management, finance, telecommunications, agriculture, and energy. The precise determination of absolute location, a cornerstone of PNT, traditionallyrelies on GNSS and their timing signals. However, a paradigm shift is under-way, powered by compact quantum sensors. Leveraging the principles of quantumphysics, these sensors encompass a wide range of functionalities, including ultra-precise atomic clocks, accelerometers, gyroscopes, magnetometers, and gravitometers. Their emergence heralds a transformative era in PNT, promising unparalleled precision and resilience, particularly in GNSS-denied environments. This imminent revolution necessitates a comprehensive exploration of quantum sensors’ capabilities and theirpotential impact on PNT.
